Originální abstrakt

The acoustic emission method is remarkable source of information about the fatigue process and its intensity under cyclic loading. Specimens made of pressure vessel steel, of Cr–Ni–Mo–V composition and INCONEL 713LC were subjected to bending fatigue loading in the high-cycle regime. This study presents results of the acoustic emission signal analysis. The main aim of this study is to propose a methodology for evaluation of the early manifestations of the fatigue damage and to identify material changes in both materials by acoustic emission parameters. An examination of the crack initiation sites and microstructure has been also performed. The comparison of acoustic emission signals indicates differences of damage mechanisms in observed materials.
